Ad hoc backup of scheduled job.

I need to re-run a windows backup that is scheduled to run every day.
I've highlighted the entry in the calendar view, selected the
properties and copied out the command into a batch file.

Running the batch file from the command prompt causes the windows
backup program to open along with the drives that need backing up
highlighted but I'm unable to press the start button. The backup
window stays open for about 2 mins then closes.

The reason I'm trying to use the stored list of drives/folders to
backup is that the selection list is long and complicated, i.e. it's
not just a case of clicking a few drives then running.
